3 Claims. (01. 206-7) My invention relates to improvements in moth bags in which articles of clothing and various articles made of textile fabrics, which are subject to the attack of moths, may be stored for the purpose of protecting the articles against injury by moths. Heretofore there have been two general types of bags for storing garments and other articles, one of which is of the envelope type. This type of bag is limited in its expansion to such an extent that but few garments can be stored in the bag at a time. The other type is what is known as the box type, wherein the bag, when extended, forms a rectangular receptacle shaped more nearly like a box, and therefore having greater depth than the envelope type of bag and for that reason it is adapted to contain a greater number of garments than the envelope type of bag although it requires but a slightly greater amount of material in the making of it.

In various types of moth bags it is customary to provide along the edges of the bag opening through which the garments are introduced, a pair of flaps which are placed against each other, face to face, when the bag is to be closed, and are then folded over one or more times upon themselves for the purpose of closingthe bag so that moths cannot get into it. These flaps are usually held in overlapping relation by suitable clips or other means. Heretofore, the box type of moth bag has been made by hand or at least a substantial part of the manufacture was a result of hand labor, and therefore this type of bag has been expensive'to make and it has been necessary to sell it at relatively high prices, thereby limiting the market for the article.

The object of the present invention is to provide a moth bag of the box type which can be made entirely by machinery and therefore it can be made at a sufiiciently low cost to permit it to be retailed at a price corresponding more nearly with that of the envelope type of bag. Where the box type of bag can be made by machinery, it is possible to sell it at a price which makes its use advantageous over the envelope type of bag because the capacity of the box type I of bag is so much greater than the envelope type that for a given number of garments they may be stored as cheaply or more cheaply in the box type of bag than in the envelope type.

Another advantage is that the garments may hang more freely in the box type than in the nv l p typ a d the Qverall le and W dth for a given capacity may be less in the box type of bag than in the envelope type.

The bags made in accordance with my present invention can be produced from a single blank of paper or cardboard stock, which may be suit- 5 ably cut and creased, or scored, at a single operation in a press, with the portions which are to form the overlapping or interlocking flaps integral with the blank which is to form the body of the bag, so that the flaps will not have to be 10 separately pasted onto the blank as has been the case in previous devices.

Under the broad principle of my invention the bag may take several dilferent forms or modifications. For instance, the door or opening 1 through which the garments may be introduced into the bag or removed therefrom may be formed on the front wall of the bag to open up in the form of a rectangular door, or the same may be formed of triangular shape so that the door member opens in the form of a triangular piece with the wider portion adjacent the top of the bag.

In another form of the invention the opening may be in the form of a straight opening down the front of the bag, composed of the overlapping flaps referred to. In another form these flaps may be disposed along a side edge of the bag. In all forms of the invention the bag may be made of a single blank and may be folded and closed by machinery if'desired. Other objects and advantages will be set forth in the detailed description of the various forms of my invention.

I will first describe the form of bag shown in Figures 1 to 6 inclusive. This bag is of the box type and consists of a body portion I of rectangular form having top and bottom walls 2, 3, front and back walls 4, 5, and end walls 6 forming a closed container having a compartment 1 for the reception of garments and other articles which are to be protected against attack from moths. I have shown the hanger 8 attached to the top wall of the bag by means of which the bag may be supported from a hook, a bar or any other form of support where the bag is to be suspended in a vertical position in order for the garments to hang in an upright position.

It will be understood that the bag may be laid on a shelf or otherwise supported but in practice it is common to support the bag on a hook.

1 The bag shown in Figures 1 to 5 inclusive is made from a blank which may be cut and scored or creased in one single operation, and the blank is illustrated in Figure 6. It consists of a sheet 8 of cardboard or paper stock of any desired weight and the stock may be treated by any of the well known processes for rendering it repellant to moths. The blank shown in Figure 6 is sub stantially a rectangle, but on opposite ends there are projecting members 9, In which form the over lapping flaps, as will be explained in detail. This blank is cut substantially to the outhne shown, and creasing or score lines are formed on the blank, preferably in the arrangement shown, al-

though as far as the broad features of my invention are concerned, variations may be made in the arrangement of the score lines. Preferably, the bag is collapsible after it has been setup so that it may bereduced to compact, fiat form for shipping and storage and may be expanded or opened In Figure 6 I have shown a rectangular blank 3 having projections 9, I3 at opposite ends, as referred to above. Extending across the blank are three score lines II, I2, I3 parallel to each other and toward the opposite end of the blank there are three similar score lines I4, I5, I6 parallel to eachother and extending from the top to the bottom of the blank. There is a score or crease line I! extending parallel with and adjacent the top edge of the blank and a similar line 20 arranged parallel with and adjacent the lower edge of the blank. 5 Inside of these two score lines there are lines I8, I9 lying parallel to the first mentioned score lines and spaced therefrom but extending only between the outermost score lines I I, I6 referred to above. In addition, there are diagonal score 10 lines 2| and 22 arranged adjacent the top as well as the bottom of the blank in Figure 6, and these are so related to the longitudinal lines as to form several triangles in relation thereto. The sections 23 of the blank lying between the score lines 10 I1, 2! and the adjacent edges of the blank will form the ends of the bag. The sections 24 to the left of the score line I I will form one half of the front wall of the bag and the section 25 to the right of the score line It will form the other half 20 of the front wall of the bag. The section 26 between the score lines II, I3 will form one end wall of the bag and the section 21 between the score lines I4, I6 will form the other end wall of the bag. The projection 9 at the left end of the 25 blank in Figure 6 is provided with score or crease lines 28 extending vertically across the same to facilitate the folding of this member in the manner hereinafter described. The projecting member H3 at the right side in Figure 6 is also pro vided with scoring or creasing lines 29 disposed vertically in the view in order to facilitate the folding of this flap. In addition there is a score or crease line 30 where the projection 3 joins the body of the blank. The blank is out along the lines 32 at right angles to the edge of the right side of the blank in order to form a door of the section 33 which has at its right hand end one of the flaps. There is a score or crease line 3| con necting the inner ends of the cuts 32 to facilitate 0 the hinging of the door along this line.

The blank may be made up into the bag form by folding the blank on the various score lines. The sections 23 will form the ends of the box, as shown in Figure 1. The sections 23 adjacent the 40 top and bottom of the blank will be folded over like the ends of a bag or box, asshown in Figure 1, and the overlapping members will be pasted or glued together to form a sealed enclosure at the top and bottom of the bag. It will be apparent that the bag may be collapsed or pressed flat as the score lines I2, 21, 22 along the side walls permit these walls to be folded for this purpose. The edge 34 will be supplied with a suitable ad hesive and when the blank is folded around into rectangular shape this glued edge will be secured against the edge 35, the two edges overlapping for this purpose along the front of the bag, as shown in Figure 5. The section 33 between the two cuts 32 constitutes the door which may be 60 opened as. shown in Figure 5 to provide an opening in the front of the bag through which garments may be passed into and out of the bag. It will be apparent that the flap 9 projects at the front of the bag vertically along the front opening adjacent/one edge of the door; the flap I0 which is formed on one edge of the door will be superimposed upon the flap 9 when the door is in closed position; and both of these flaps in over-' lapping relation may be folded upon themselves along the crease lines 28, 29. The folded flaps may be held in this position by means of the clips 36, which are attached to the door. in position to engage the'folded flaps. In order to seal the top and bottom edges of the door, flaps 31 are pro- V 2,022,941 'vided along the top and bottom edges of the door and corresponding flaps 38 are attached along the top and bottom edges of the opening 39.

These flaps cannot be out out of the material shown in Figure 6 and must be glued thereon after the blank has been formed. They may be glued along the edges of the door and of the front wall respectively. They are also adapted to be folded upon themselves as shown in Figure 1, and suitable clips 40 are provided on the door for holding these flaps in position.

Whenever the bag is to be opened the several clips 36, 49 are slid back to disengage from the several flaps, the flaps on the vertical as well as the horizontal edges of the door are then unfolded, and the door may be opened, as shown in- Figure 5. To close the door these several operations are reversed.

In Figures 7 to 9 I have shown a modified construction in which the door is of triangular shape, the other features of the bag corresponding with that shown in Figures 1 to 6. For this purpose there is a single cut made at 4| extending inwardly from the right hand edge of the blank, and a crease line 42 extends from one end of this cut diagonally to the outer edge of the blank as shown in Figure 9, leaving a triangular section 43 to form the door. The fla'ps 9 and I0 are formed and creased the same as before, and in other respects the device is the same as the first construction. When the bag is closed, as shown in Figure 7, the flaps 9, I ll are folded upon themselves and are held by the clips 36 which are mounted on the door. Folding flaps 44,45 are attached on the top of the door and the adjacent edge of the opening 46, and these flaps may be made of separate pieces attached to the blank. When the door is open, as shown in Figure 8, it will be in the form of a triangle leaving a triangular opening 46 through which garments may be passed into or removed from the bag.

In this form of the invention the lower flaps 31, 38 shown in Figures 1 to 6 are eliminated, thereby making it necessary to provide only the flaps 44, 45 in addition to the single piece from which the bag is made.

In Figures 10 and 11 I have shown the opening I provided at one of the corners of the bag. In this case the bag is provided with an opening 41 along one of its vertical edges and the blank is provided with extensions 48, 49 to form flaps, one along each side of the opening, which flaps are adapted to be folded in overlapping relation upon themselves, and to be held by the clips 59 arranged adjacent the ends of the flaps, and at the points intermediate thereof. In this case there is no door to be swung open, but the bag is simply opened by releasing the flaps and separating the adjacent edges of the bag sufficient to place a garment into the bag through the opening.

In Figures 12 and 13 I have shown a bag Sim-- ilar to the one shown in Figures 10 and 11 except that the flaps extend the full length of the bag, top to bottom, and the side walls of the bag are made to collapse. In this case the flaps 5!, 52 arranged at one corner of the bag are adapted to be folded together upon themselves, as shown in Figure 13, and to be held by the sliding clips 53.

In Figures 14 and 15 I have shown a type of bag wherein the opening is provided at the middle of the front wall of the bag. In this case the front wall is provided with an opening 54 extending vertically thereof and the blank is provided with flaps 55, 56 projecting from the blank along the edges of the opening 54 there being no door in this construction. These flaps are adapted to be folded over upon themselves as shown in Figure 14 and to be held by means of the clips 51.

In Figures 16, 17 and 18 I have shown a bag with the opening arranged along one of the side walls. In this case the blank shown in Figure 18 is provided with the extension flaps 58, 59 at opposite sides, the flaps being provided with vertical score or creaselines 60 to facilitate the infolding of the flaps. At the left of the blank cuts are made, as shown at 6| so that the flap 58 will be separated from the marginal members 62 to permit this to be overlapped on the opposite side edge 63 for gluing the bag together and to leave the flaps extending from the edges of the opening when the bag is made up as shown in Figure 17. This type of bag is folded on the various score and. crease lines, as shown in Figure 18, so that the end members are folded upon themselves and glued or pasted as shown at 64. in Figure 16. The side walls are provided with crease lines 65 to permit these walls to be collapsed for folding the bag in flat position. The flaps 58, 59 are adapted to be folded upon themselves and to be held by the clips 66.

It will be apparent from the above that I have provided bags in various forms, with the flaps formed integral with the bag blank along the edges of the opening of the bag, so that these flaps do not have to be made separately and pasted onto the blank, except possibly those flaps which are arranged at the top and bottom of the several doors. Where there is no door the flaps are made integral with the blank and it is unnecessary to apply any strips to the blank and the bag in such cases may be made entirely by machinery and without hand labor.

Having described my invention, what I claim is:

1. An article of the character described, comprising a bag formed of sheet material, scored or creased and folded into a box-like container, said blank having projections or extensions at opposite side edges of said blank and of less length than the blank, to form projecting flaps, said blank having a cut extending inwardly from one side edge adjacent one end of one of said extensions and having a crease or score line extending diagonally from the inner end of said out to the adjacent edge of said blank upon which the blank may bend the material lying between said out, said score or crease line and the edge of the blank forming a door of substantially triangular shape with one of said flaps disposed on the free edge of said door, the opposite edges of said blank above and below said extensions being overlapped and secured together, said flaps being foldable together upon themselves for the purpose of' closing the bag along the edge of said door when the latter is in closed position.
